Defold wont run 1.64

Questions
#1

Hi, I am a new user here but having issues at step one. I have spent 2 hours trying to get the program to run on Windows 100 but double clicking teh defold.exe does nothing. I have tried:

-rebooting
-re-downloading
-running with administrator rights
-Putting the Defold directory in various directories (C:/,D:/ drive roots etc)
-Re-installing /Updating Java manually
-Completely removing the separate installation of Java
-Swicthing off antivirus program
-Adding Defold to Windows defender whitelist

…but it still does nothing when I double click on it. Any ideas? I am on Windows 10 latest update. 32 Mb Ram, i7.

I cant seem to edit my posts on this forum either, so I shall just say that Windows 100 = Windows 10 :slight_smile:

The recommendation is to put it somewhere in user home, for instance on the desktop

Defold comes packaged with a Java version. No need to install one.

Could you please try to open Defold.exe from the command line?

I put the folder on the desktop and try to run from the command line but absolutely nothing happens…

Additionally I tried the steam version. That does nothing either. :frowning:
I haven’t had any issues with any other programs not running on my PC.

#6

Here I try double clicking the steam version 3 times… It just stops immediately…

You might be able to find out some kind of log/error/warning by looking around the Windows Event Viewer software.

The editor keeps a log file. Might be worth a look

C:\Users\<username>\AppData\Local\Defold\

Thanks. Lots of lines like this:

then this:

The solution is this:

  1. Navigate to C:\Users\<username>
  2. Open the file called .accessibility.properties using a standard text editor (Notepad is fine)
  3. Find the following lines in the config:
  4. assistive_technologies=com.sun.java.accessibility.AccessBridge
  5. screen_magnifier_present=true
  6. Add a hashmark (#) in front of theses lines
  7. Save your changes to the file, restart the User Client Software

Correct. That assistive technology software is somehow not compatible with Javafx. Also mentioned in our FAQ:
